Companies in the construction industry are using new technologies to make concrete ultra-durable, while others are turning to biology to make sustainable biocement.
As an example, one company is developing ultra-high-durability concrete (UHDC). It contains crystalline additives, alumina nanofibers, and cellulose nanocrystals that allow it to self-heal and withstand extreme conditions.
Another innovation called biocementation involves stimulating bacteria’s growth and metabolic activity by providing them with nutrients and cementing agents. The resulting enzymes produced by the bacteria cause reactions that form substances such as calcium carbonate, which bind the soil particles together.
While it may take more years for the construction industry to routinely used these new techniques, they will indeed address long-term challenges in construction. These developments will also significantly lower greenhouse gas emissions as we move away from the traditional processes.
